Hi Daniel, I have "Image Data Converter" on my PC, but I cannot remember if it came with my Sony Alpha or I loaded it free. It has some basic functions, but most importantly allows you to convert RAW files into other formats (Tiff, JPEG), and then sharpen and enhance the images. I now shoot RAW, and convert to TIFF format, which means that an image from my Sony Alpha 700, converted from RAW into TIFF is typically around 20 MB - 25 MB before I start cropping.
I am still a complete novice at all this, but the image quality compared to straight JPEG does not bear comparison. There is less pixellation, noise and the colours seem more vibrant.
